NANO โ #NEXTGENERATION Lime & CO2 Industry
๐ฆ๐ผ๐น๐ฎ๐ฟ ๐ก๐๐ก๐ข lime burning reactor
Leveraging the abundant and renewable sun power, NANO is trailblazing the way towards a sustainable future for the lime industry.
Our 0,5MW NANO prototype tested during the experimental campaign at the Paul Scherrer Institute has demonstrated the viability of this game-changing approachSince year 2000 QualiCal has been focused on CO2 Mitigation in the Lime Industry, replacing Fossil Fuels with Concentrated Solar Energy.
Solar NANO is using concentrated solar energy as process heat for the thermal decomposition of limestone to produce lime in order to help reduce CO2 emissions in the lime industry.
Can we develop a solar reactor that will โฆ
- calcine limestone with a high degree of calcination?
- produce lime with any desired reactivity?
- efficiently use sunlight to drive the calcination reaction?
- operate reliably under the severe conditions of solar energy?
The results of 2000โ2003 research program
QualiCal already explored the possibility to produce lime using concentrated solar energy in co-operation with PSI โ Paul Scherrer Insitute designing, constructing and testing a 10 kW reactor prototype in a solar furnace.
- More than 100 hours of reliable reactor operation in PSIโs solar furnace.
- Solar produced lime meets industrial standards
- Degree of calcination exceeded 98%.
- Any lime quality ranging from low to high reactivity may be produced.
The Future of Solar lime production
We are motivated to consider a solar lime production process.
Our early research results strongly suggest that the process is technically possible.
We recognize that there is some distance to go before we can realize a large-scale solar lime plant. But we also recognize that there is an enormous amount of solar radiation bathing the earth.
Furthermore, we have the opportunity to work with 1- 5 mm limestone particles for producing a high purity lime product. The highly endothermic high temperature process is a means of using the most abundant energy resource on the earth to produce a product valuable to we citizens of the earth with minimal CO2 emissions.
- Solar calcination process is technically possible.
- Calcination of 1โ5 mm particles that are not normally calcined.
- Solar process produces a pure CaO product.
- CO2 mitigation potential is substantial.
- Sufficient quantity of sunlight is available to meet world needs.
